引入射弹单位面积的冲击动能和靶体单位侵彻体积的冲击动能，结合钢纤维混凝土靶的实验数据，考察了两者之间的关系。

The kinetic energy of per unit penetration volume and the impact kinetic energy per unit cross section are introduced to review their relation by dealing with the experimental data.

当长杆射弹和撞击速度都相同时，与侵彻钢纤维混凝土靶相比，含单层密排刚玉球的钢纤维混凝土靶中的侵彻深度大约降低了11%，而水泥砂浆石靶中的侵彻深度增加了12%。

The penetration depth into SFRC with the board is decreased about 11%, but the penetration depth into cement mortar is increased about 12% as compared with that into the SFRC.
